![]() The two next tools enable to zoom in the panorama and view the pre-stitched panorama into the preview of your operating system. It doesn't always look so good.Ĭ - It is thus very simple once understood how the software gathers photos from a same panorama, which we'll see again later.ĭ - The little arrow downward enables to select more geometric projections. Caution: if the photo's been shot with a short focal, the image seems very stretched at the top and the bottom of the panorama. For all the photos with a field of view over 100°. The edges of the image remain homothetic. ![]() All straight lines curve apart from the skyline. All lines remain straight but the panorama is very distorted at the edges with a field of view above 100°.ī - The cylinder stands for cylindric projection. ![]() I thus recommend you to read my page dedicated to geometric projections to see which influence your panorama has on the choice of this projection.Ī - The rectangle thus stands for rectilinear projection also called straight or orthoscopic. It is possible to choose directly among the three main geometric projections: rectilinear (straight geometry, interesting for panoramas below 100-110°), cylindric projection (curve quite stretched in height) and spherical (curved but more compressed). For specialists! 3 - Choice of geometric projection To get this result, we just had to tilt the body slightly during the shooting.ĭ - And finally, the last icon, under the form of the figure 123, enables to move the panorama in Yaw, Pitch and Roll with numerical values. We saw in the generalities that it wasn't of any use. It allows to keep the edges of the buildings straight, as if you'd used a shift lens when shooting. Try it.ī - The fourth icon is used to straighten the panorama. Tip! For these icons to be accessible, it is important to choose a geometric projection under the form of an icon, just on the right of this serial of tools: "Rectilinear", Cylindric" or "Spherical".Ī - The first icon is used to enlarge the panorama in the width of the workspace.ī - The second icon is used to center the panorama on the center of the workspace. In the second set of icons, you'll find tools enabling you to center the panorama or level it (automatically or not). It becomes the new flight point of the panorama. Try and see.Ĭ) Fourth icon (cross-shaped): if you click this icon, you can then click anywhere in the panorama to center it on this new point. It's important to remark that this moving is then done on a virtual sphere. You'll then be able to move it as you want.ī) Third icon: if you click this icon, you'll move the whole panorama at once. For that, click the first icon in the toolbar then click on one photo of the panorama. When the second, third or fourth icon is selected, one click on the first enables to select a photo in the pre-stitched panorama, just below, in the workspace.Ī) Second icon: enables to select one image in the panorama. There are seven different parts in the toolbar. Numerous tools can be accessed via a set of icons that we'll see in details now. And finally, and that's a real asset of PTGui, it is possible to select the zones where pedestrians have moved for instance and could bring blurred zones or characters selected into the final panorama by eliminating them from pre-stitching, directly in pre-stitching. Into the Panorama Editor, it is also possible to improve the placement of images relatively to one another manually, especially when consecutive images lacked raw material to automatically place checkpoints. You still have the classic cylindric, spherical or rectilinear ones, but so many more have been added. The most important of them is in my opinion the choice of the geometric projection. PTGui's " Panorama Editor " enables to make numerous aesthetic, technical or linked to checkpoints modifications. As its competitor Autopano Giga, PTGui enables experienced users to edit the pre-stitched panorama to have an ideal and optimized final rendering.
